Problems solved by technology

[0009] The above-mentioned patent documents are advantageous in that, in the case of an overcurrent flowing in the secondary battery, components mounted on the path of the current flowing in the secondary battery break quickly, thereby interrupting the overcurrent, thus ensuring the safety of the secondary battery in use , but there is a problem that it is not easy to bond the metal plate and the metal bridge to each other, since the metal plate and the metal bridge are dissimilar metals, and therefore the metal bridge must be bonded to the metal plate to wrap the upper and lower surfaces of the metal plate with the slit Adjacent areas, so the part is structurally unstable, has low resistance to external impacts, and is not easy to manufacture

Embodiment Construction

[0043] In this application, it should be understood that the terms "comprising", "having", "including" etc. indicate the presence of the stated features, numbers, steps, operations, elements, components or combinations thereof, but do not preclude the presence or addition of one or more Other features, numbers, steps, operations, elements, components or combinations thereof.

[0044]Furthermore, the same reference numbers will be used throughout the drawings to refer to components that perform similar functions or operations. When it is said in the specification that one component is connected to another component, not only the one component may be directly connected to the other component, but also the one component may be indirectly connected to the other component via the other component. Furthermore, the inclusion of an element does not mean the exclusion of other elements, but rather means that those elements may be further included unless otherwise mentioned.
